A New Oil Soluble Temporary Plugging Agent

Wanzhuang Branch of RIPED, Langfang City, Hebei 065007, china

摘要

摘要: 为降低高闭合应力储层暂堵压裂施工压力高、砂堵风险大等难题,同时为进一步提高非常规致密油气单井的产量,研究形成一种新型暂堵剂ZD-150。该暂堵剂抗温性能可达到120℃,48 h油溶率大于95%,24 h酸溶率小于5%,0.2%瓜胶携带15%的暂堵剂悬浮稳定时间可达12 h,且具有抗压性高和暂堵效果好的特点。现场10多井次应用表明:ZD-150通过与粉陶结合,可将施工的转向效果提高1.5倍,改造后效果提高2.1倍,为非常规储层体积压裂模型下提高裂缝复杂程度提供了新型材料。

Abstract: A new temporary plugging agent, ZD-150, was developed to overcome the high operational pressure and high risk of sand plugging in fracturing job in high closure stress reservoirs. ZD-150 can stand temperatures to 120℃, and has oil solubility of greater than 95% in 48 h, and acid solubility of less than 5% in 24 h. Suspension of 0.2% guar gum solution containing 15% ZD-150 remains stable for 12 h, with no sedimentation. ZD-150 has high compressive strength and good temporary plugging performance. The application of ZD-150 in 10 wells showed that, by combining with ceramic powder, the turnaround efficiency of the operation was enhanced by 1.5 times, and even by 2.1 times after further modification. ZD-150 is a new additive for use in increasing the complexity of fractures in SRV fracturing.
